Description

Technical Field

[0001] This utility model relates to the field of noise and vibration control technology, specifically to a sound-insulating soft-pack support structure suitable for the air inlet and outlet of suspended high-noise rotating equipment. Background Technology

[0002] In the power and petrochemical industries, the encapsulation of high-noise rotating equipment is of great significance for reducing noise and improving the working environment. However, the implementation of this solution currently faces many challenges, mainly due to two major industry restrictions.

[0003] From a safety regulations perspective, it is explicitly prohibited to perform hot work (such as welding and cutting) or live-line operations in the work area. This requirement aims to protect the lives of workers and prevent accidents such as fires and explosions caused by hot work, as well as the risk of electric shock caused by live-line operations. However, this also greatly limits the application of traditional fixing methods, making it impossible to implement some installation methods that rely on welding or live-line work.

[0004] Regarding the load-bearing requirements of the equipment structure, the use of intrusive fixing methods such as expansion bolts is strictly prohibited for the platform parts of rotating equipment. This is because expansion bolts can damage the platform structure during installation, weakening its structural strength and affecting the safe and stable operation of the equipment. Furthermore, expansion bolts have poor sealing performance, easily leading to sound leakage and failing to effectively achieve noise reduction goals. In practice, using expansion bolts to fix noise-reducing materials is time-consuming and labor-intensive to disassemble, severely impacting operational flexibility. Moreover, this type of fixing method has low reusability, increasing costs. More importantly, excessively heavy components may transmit vibrations, further causing structural strength problems and posing potential safety hazards to the equipment.

[0005] In summary, existing solutions for covering the underside of high-noise rotating equipment platforms in the power and petrochemical industries are difficult to implement due to industry limitations and the drawbacks of traditional fixing methods. Therefore, it is urgent to develop a safe, efficient, non-destructive, and well-sealed covering and fixing technology to meet the dual requirements of noise reduction and structural safety for high-altitude compressor platforms in industrial production. Utility Model Content

[0006] The purpose of this invention is to provide a sound-insulating soft-pack support structure suitable for the air inlet and outlet of suspended high-noise rotating equipment, so as to solve the problem that the existing expansion bolt intrusive fixing method will damage the platform structure and noise reduction materials.

[0009] The bottom support includes an internal steel frame and multiple small steel frames installed on the outer edge of the steel frame. The multiple small steel frames are connected end to end to form a closed loop. The top of the small steel frame is equipped with a pressure plate for installing the rotating equipment platform and the noise reduction jacket. Multiple mounting holes are evenly opened on the small steel frame, and the bottom of each mounting hole is equipped with an adjustment component for adjusting the pressure plate.

[0010] Furthermore, the adjusting assembly includes an adjusting bolt and a first nut fitted thereon, a second nut at the bottom of the first nut, a small steel frame at the top of the first nut, and a pressure plate installed on the top of the adjusting bolt.

[0011] Furthermore, guide columns are provided between the pressure plate and the small steel frame.

[0015] Furthermore, the T-shaped bracket includes a transition bracket connected to the inside of the small steel frame, with a vertical bracket on the side of the transition bracket and a T-shaped mounting bracket on the top of the vertical bracket.

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please refer to Figure 1-6 This utility model provides a sound-insulating soft-pack support structure suitable for the air inlet and outlet of suspended high-noise rotating equipment, and its specific implementation is as follows:

[0028] The sound-insulating soft-pack structure mainly consists of two parts: a bottom support 10 and a T-shaped support 20. The bottom support 10 serves as the basic support unit for the entire structure, supporting the rotating equipment and its external noise-reducing material; the T-shaped support 20 is used for fixed connection with the rotating equipment platform to ensure the stability of the entire structure.

[0029] The bottom support 10 is constructed as follows: Standard square steel profiles are used as the main steel frame 1. The steel frame 1 consists of multiple steel frames fixed together with bolts, forming a herringbone structure. This structure ensures both support strength and ease of installation and disassembly. Multiple smaller steel frames 2 are evenly distributed along the outer edge of the steel frame 1. These smaller steel frames 2 are connected end-to-end with bolts to form a closed-loop structure. In this embodiment, the closed-loop shape is hexagonal, but it can be adjusted to other polygonal structures depending on actual needs.

[0030] Each small steel frame 2 has a pressure plate 5 on its top, which is used to mount the rotating equipment platform 3 and the noise reduction jacket 4. To allow for flexible adjustment of the pressure plate 5, multiple mounting holes are evenly spaced on the small steel frame 2, and each mounting hole has an adjustment component at its bottom. The adjustment component consists of an adjusting bolt 21, a first nut 22 fitted onto the adjusting bolt 21, and a second nut 23 at the bottom of the first nut 22. Rotating the first nut 22 adjusts the height of the pressure plate 5 to accommodate rotating equipment platforms 3 of different thicknesses. The top of the first nut 22 is in close contact with the small steel frame 2 to ensure stability during adjustment. The pressure plate 5 is mounted on top of the adjusting bolt 21 and moves up and down by rotating the adjusting bolt 21.

[0031] A guide post 7 is provided between the pressure plate 5 and the small steel frame 2. The function of the guide post 7 is to ensure the stability of the pressure plate 5 during movement and prevent it from shifting or tilting. At the same time, a sealing material 6 is provided between the rotating equipment platform 3 and the pressure plate 5. The function of the sealing material 6 is to fill the gap between the two and prevent noise leakage.

[0032] The connection between steel frame 1 and small steel frame 2 is as follows: steel frame 1 has pre-drilled connection holes, and the end of small steel frame 2 is fixed to the connection holes of steel frame 1 with bolts. This connection method ensures the stability of the structure and facilitates subsequent disassembly and replacement.

[0033] The T-shaped bracket 20 is specifically constructed as follows: it includes a transition bracket 201 connected to the inner side of the small steel frame 2, a vertical bracket 202 at the side end of the transition bracket 201, and a mounting T-shaped bracket 203 at the top of the vertical bracket 202. The transition bracket 201 and the small steel frame 2 are fixed together by bolts to ensure the integrity of the T-shaped bracket 20 and the bottom bracket 10. The transition bracket 201, the vertical bracket 202, and the mounting T-shaped bracket 203 are also connected by bolts for easy installation and disassembly. The T-shaped bracket 20 can also be a one-piece molded design.

[0034] During installation, the steel frame 1 and small steel frame 2 of the bottom bracket 10 are first assembled with bolts to form a complete bottom support structure. Then, the rotating equipment platform 3 is placed on the pressure plate 5, and the height of the pressure plate 5 is adjusted using adjusting bolts 21 to ensure tight contact between it and the rotating equipment platform 3. Sealing material 6 is filled between the rotating equipment platform 3 and the pressure plate 5 to ensure a tight seal. Finally, the adapter bracket 201 of the T-shaped bracket 20 is fixedly connected to the small steel frame 2, the vertical bracket 202 is connected to the mounting T-shaped frame 203, and the mounting T-shaped frame 203 is securely fastened above the rotating equipment platform, completing the installation of the entire soundproof soft-pack structure.

[0035] In terms of material selection, both steel frame 1 and small steel frame 2 use standard square steel profiles, which have advantages such as high strength and corrosion resistance, meeting the requirements of high-noise rotating equipment in the power industry. The pressure plate 5 is made of high-strength steel plate to ensure it can withstand the weight of the rotating equipment platform 3. Adjusting bolts 21, the first nut 22, and the second nut 23 are all standard fasteners to ensure connection strength and stability. The sealing material 6 uses rubber or silicone with good sealing performance to ensure a tight seal between the rotating equipment platform 3 and the pressure plate 5.

[0036] In terms of manufacturing process, both steel frame 1 and small steel frame 2 are processed using cutting and welding techniques to ensure dimensional accuracy and connection strength. Pressure plate 5 is processed using stamping or casting to ensure flatness and strength. Adjusting bolt 21, first nut 22, and second nut 23 are manufactured using standard fastener production processes to ensure their quality meets standard requirements. Sealing material 6 is made from suitable rubber or silicone materials selected according to actual needs and processed using injection molding or extrusion techniques.

[0037] For installation and commissioning, firstly, the steel frame 1 and small steel frame 2 of the bottom bracket 10 need to be assembled and adjusted to the appropriate position and height. Then, the rotating equipment platform 3 is placed on the pressure plate 5, and the height of the pressure plate 5 is adjusted using the adjusting bolts 21 to ensure tight contact between it and the rotating equipment platform 3. Sealing material 6 is filled between the rotating equipment platform 3 and the pressure plate 5 to ensure a tight seal; sealing rings can be selected as the sealing material 6. Finally, the adapter bracket 201 of the T-shaped bracket 20 is fixedly connected to the small steel frame 2, the vertical bracket 202 is connected to the mounting T-shaped frame 203, and the mounting T-shaped frame 203 is securely fastened above the rotating equipment platform, completing the installation and commissioning of the entire soundproof soft-pack structure.

[0038] This soundproof soft-pack structure achieves sound insulation and noise reduction for the air inlets and outlets of rotating equipment through the coordinated action of the bottom support 10 and the T-shaped support 20. The bottom support 10 serves as the basic support unit, bearing the rotating equipment and its external noise-reducing material; the T-shaped support 20 is fixedly connected to the rotating equipment platform, ensuring the stability of the entire structure. Simultaneously, the design of the adjustment components allows for flexible adjustment of the pressure plate 5, adapting to rotating equipment platforms of different thicknesses and sizes. The filling of the sealing material 6 further enhances the sound insulation and noise reduction effect of the structure. The entire soundproof soft-pack structure has advantages such as structural stability, convenient installation, and good sound insulation and noise reduction effect, making it suitable for noise reduction treatment of the air inlets and outlets of high-noise rotating equipment in the power industry.

[0039] In addition, this sound-insulating soft-pack structure also has the following characteristics:

[0040] Modular design: Both the bottom bracket 10 and the T-shaped bracket 20 adopt a modular design, which facilitates installation, disassembly, and transportation. The components are connected by bolts, eliminating the need for on-site welding or drilling, thus reducing construction difficulty and cost.

[0041] Adjustability: The design of the adjustment components allows the height of the pressure plate 5 to be flexibly adjusted according to the thickness of the rotating equipment platform, ensuring the adaptability and versatility of the structure.

[0042] Sealing performance: The filling of sealing material 6 enhances the sealing performance of the structure, effectively preventing the transmission and leakage of noise.

[0043] Durability: The use of high-strength materials and standard fasteners in manufacturing and connection ensures the durability and stability of the structure.

[0044] In summary, this sound-insulating soft-pack structure, through the synergistic effect of the bottom support 10 and the T-shaped support 20, as well as the design of the adjustment components and sealing material 6, achieves sound insulation and noise reduction for the air inlet and outlet of rotating equipment. This structure has advantages such as structural stability, convenient installation, and good sound insulation and noise reduction effect, and is suitable for noise reduction treatment of high-noise rotating equipment in the power or petrochemical industries.
